Application filed July 29, 1914-. Serial No. 853,874.

To all whom it may concern:

Be it known that 1, WILLIAM T. KING, a citizen of the United States,residing at ltosanky, in the county of Bastrop and State of Texas, haveinvented certain new and useful Improvements in Vises and Saw- Clamps;and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to saw clamps and vises, and one of the principalobjects of the invention is to provide a simple vise and clamp to beoperated by a foot pedal, and which will. quickly and firmly engage anyarticle placed between the jaws and which can be readily operated forreleasing the article clamped, and which will be simple in construction,reliable and eflicient in use and which can be manufactured atcomparatively low cost.

The foregoing and other objects may be attained by means of theconstruction illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation of a vise and saw clamp made in accordancewith this invention, and Fig. 2 is a detail sectional view on the line2-2 of Fig. 1.

Referring to the drawing, the numeral 1 designates a standard having itslower end screw threaded as at 2 for engagement with a suitable base orsupport. The standard 1 is provided with a curved upper end 3 having ajaw member 1 formed thereon or connected thereto. The companion jawmember 5 is formed on an arm 6 pivoted at 7 to the standard 1 andprovided with a lever or extension 8 which is pivotally connected at 9to a link 10. A spring 11 connected to the standard 1 bears against thelever 8 to open the jaws 4- and 5. The link 10 is connected to a curvedmember 12, said link being pivoted upon a pin 13 to the curved member 12and said member being pivoted at 14; to the standard 1 and slightlyspaced there from by a block as shown. A link 15 is pivoted at 16 to thecurved member 12 at one end and the opposite end is bent backwardly at17 and pivoted at 18 to a foot lever 19. The foot lever 19 is pivoted at20 to the standard 1, and is provided upon its upper surface with aseries of ratchet teeth 21, while the outer end of the lever isflattened at 22 to form a foot rest.

A pawl or engaging member comprises an arm 23 pivoted at 24: to thestandard 1 and provided with a curved downwardly extending portion 25having an aperture 26 therein through which the foot lever 19 extends.Connected to the curved portion 25 of the arm 23 is a pawl or stop 27designed for engaging the ratchet teeth 21 when the foot rest 22 isdepressed for closing the jaws of the vise or clamp. The pawl 27 isprovided with an outwardly projecting pedal 28 for holding the pawl 27in engagement with the teeth 21, and the pedal and pawl are connected bymeans of a suitable bolt 29 to the arm 23 at the curved portion thereof.

A spring 30 is connected at one end to a ring or eye 31 on the arm 23,while the opposite end is connected to a ring or eye 32 attached to thestandard 1.

The operation of the invention may be briefly described as follows: Whenthe article to be clamped is placed between the jaws 4 and 5, the footis placed upon the foot rest 22 and by pressure the jaws are closed andthe pedal 27 is pressed down by the foot to engage with any one of theteeth 21 to hold the article between the jaws. When it is desired torelease the article, the foot rest 22 is pressed down and the spring 30will draw upward on the arm 23 and the spring 11 will open the jaws 4and 5.

From the foregoing it will be obvious that a device made in accordancewith this invention may be used conveniently as a vise or as a sawclamp.

Various changes may be made in the details of construction withoutdeparting from the spirit and scope of the invention as de fined in theclaims.

What is claimed is 1. A vise comprising a standard having a jaw formedthereon, a lever pivoted to the standard and provided with a jaw, a linkconnected to said lever, a curved member to which said link is pivoted,said curved member being pivoted to the standard and provided with alink connected to the opposite end thereof, said link being pivoted atits lower end to a foot lever, said foot lever being pivoted to thestandard, and provided with a series of ratchet teeth thereon and a footrest, an arm pivoted to the standard and provided with a pawl connectedthereto and an aperture through which the foot lever extends, and aspring for holding the jaws open.

2. A vise and saw clamp comprising a standard, a aw member connectedthereto,

a companion jaw pivoted to the standard and provided with a link and acurved mem flopieaof this patent may be obtained for five cents each, byaddressing the Commissioner standard, provided with a jaw, a member 20provided with a aw VVILLIAIH T. KING. Witnesses F. V. MORGAN, G. E.WIEST.
